To ALL WHOM ITiMA'YeoNcERN; Y p f Beit known vthatI, yl3I' N.T Ai/IIIN BORDMA'N, of Malden, county of Middlesex, andState 'of Massachusetts,

havein ventedfa'newland usefulImprovement in Coffee-Pots; and-I do hereby declare that.the following isi-a full, clear, 4and exact description thereof, which will enable others slilled in the art to make and usethe saine;

Vreference `tbenighad to the accompanying drawing, forming a part of this specitication. YThis invention relates to a new anfl'useful improvernentjin c'oi`ce-pots, as hereinafter fully shown and described, whereby the steam and .aroma which rise from the coffee during the process of boiling are condensed and saved, or not allowed to escape.

The means whereby 4this result is attained is' extremely simple, and may be applied to a coffee-pot of the most simple construction.V f It consists of a condensing-chamber, constructed oftin or other suitable material',

'and of such a sizea-ndshape that il: may be fitted Asteam-tight on the top' of the coffee-pot, s o as to coverboth i the top o'f the pot* and the nozzle or spout thereof, said ehamber,'when the coee reaches orinearly reaches the hoiling-point, being` filled with cold water or' other suitable liquid, so as tocondense the vapor or steam rising `from the coffee, and'thereby eieetually.preventy its escape.

The accompanyingdrawing represents a side'sectional view of myA invention. A is the body or mainportion of the coffee-pot, B the handle, and C the nozzle or spout thereof, the opening between which and the body A ofthe pot is covered with wire cloth, a, or, in lieu ofV this, a perforated partition The pot thus constructedis similar tof if not identical with the ordinary cheap coffee-pots in use.

The coffee-pot is provided with an ordinary lid or cover, CX, which is fitted on the pot when my invention is not applied or is -not'in use.`

i 'The coffee is ground in the usual way, and placcdin the pot with the requisite quantity of water, and the pot placed on a stove or 'over a'suitahlo'ire to boil, and -jfust previous to the contents of the pot reaching the boiling-point, a cup, D, is fitted on the top ofthe pot', said cup covering the top ofthe body, A, of Athe pot, and' also the spout or nozzle C, as shown clearly in the drawing. Y '.lhiscupA has a quantity of cold water or other liquid or substance placed into it, of a' sufllciently low temperature to condense the vapor ,and'aroma rising from the boiling contents of. the pot, and the condensed vapor and aroma pass back or down within the pot. After the strength of the coffee is obtained or'extracted, the pot is removeclfrom the lire and the contents allowed to cool, when the cup D is removed, and the lid or cover CX placed on it.' The coffee `may then be poured from the pot ns it isused. u I Y kThe great advantage of this invention is its simplicity, eheapness, and the capability of its appllicationto any ordinary coffee-pot. It answers the saine purpose as the pretcntiousand expensive devices hitherto employed to effect .the saine end. i

Having thus dscrihedmy invention, what I claim as new, and'dsire to secure by Letters Patent, is The cup or condensing-chamber D, constructed and applied to an ordinary coffee-pot, A, in the manner substantially as and for the' purpose herein set forth.
